摘要
本文通过亲虾越冬大规模人工育苗的生产性试验,总结了适用于生产的育苗技术措施:通过分类管理可以适时并相对集中地获卵;为提高育苗的成活率,采取低温产卵、适温孵化、上限育苗”的控温技术。赵冬亲虾可以多次产卵。
The main techniques in larva production of Penaeus Chinensis of a larger scale by using arfificial overwintering seedstock are summarired as follows: 1.Selecting the Qecording to their degree of maturation so as to controll them to Spawn Synchronically 2.Taking the measures of lower tempecature spawning mod- erate temperacure and rearing larva in the upper limit temperature to raise the Lar- va survival rate. 3.Controlling the pregrant females to Spawn repeatedly
